yes there are, i think..... you have to downgrade to 4.1. The 4.2 update is such a pain, that it can even mess with modchips. Wii thats are hardmodded on system menu 4.2 can now only play games from their wii regions.

I have a Japanese version Wii which i have first updated to 4.1J as required by some backup games. The D2Ckey still function and i could still play.I have recently updated to 4.2J because of Wii Shopping channel and now my Wii wouldn't play any backup games or North American games. Any help?
